Traditionally, rockets use cryogenic (super-cold) oxygen and hydrogen.
A liquid-fuel rocket or a liquid rocket is a rocket with an engine that uses propellants in liquid form.
Liquid hydrogen is a common fuel used in rocket engines.

The three types of rocket fuels are liquid rocket fuel, solid rocket fuel, and hybrid rocket fuel. Liquid rocket fuel consists of liquid components that are combined and ignited to produce thrust. Solid rocket fuel is a mixture of solid components that burns to produce thrust. Hybrid rocket fuel combines elements of both liquid and solid rocket fuels.
Robert Goddard invented the first liquid-fueled rocket engine in 1926. The liquid fuel he used was a combination of gasoline and liquid oxygen. This innovation paved the way for modern rocket technology.
Two common elements found in rocket fuel are liquid oxygen (O2) and liquid hydrogen (H2). When these two elements are combined and ignited in the rocket engine, they react to produce a powerful thrust that propels the rocket into space.
There are solid rocket fuels, and there are liquid rocket fuels.
